尝试选择最低MIN（）行中的所有字段（）

Question

我无法尝试选择最低价格和唯一的url在同一行中，此时它从第一行获取unique_url。

SELECT 
    MIN(price), `unique_url` 
FROM `product_price` 
WHERE `barcode` = '" . $product_barcode . "' 
    AND `active` = '1' 
GROUP BY `user_id` 
ORDER BY `price` ASC 
LIMIT 1 

帮助！

Answer 1

试试这个

SELECT MIN(price) as mPrice, `unique_url` 
FROM `product_price` 
WHERE `barcode` = '" . $product_barcode . "' AND `active` = '1' 
GROUP BY `user_id` 
ORDER BY mPrice ASC 
LIMIT 1
